Restore Peak Performance to Your GM Vehicle
Is your trusty 1996 GM vehicle suddenly acting up? Unexplained stalling, erratic transmission shifting, a persistent check engine light, or a complete no-start condition can be incredibly frustrating.

Don’t let a faulty computer keep your car off the road. This professionally prepared engine computer is the reliable, straightforward solution to bring your vehicle back to life.

A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty module is a likely culprit:
- Severe drop in fuel economy

Expert Insight: The Critical Role of VIN Programming
A common mistake we see is grabbing a used PCM from a salvage yard. While it might look identical, it’s programmed for a different vehicle’s specific options and anti-theft system (VATS). This inevitably leads to a no-start condition and more headaches. Our process of programming the module to your specific VIN isn’t just a convenience—it’s the critical step that makes this a true, effective repair. A properly Programmed 16211539 PCM is essential to bypass these issues, saving you significant time, money, and frustration.
Frequently Asked Questions
Do I need to do any programming myself?
Absolutely not. This module arrives fully programmed to the VIN you provide during checkout. The installation is plug-and-play, requiring no special tools or dealer intervention. Simply disconnect the battery, swap the modules, and reconnect the battery.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add this to the order notes or reply to your order confirmation email. We cannot ship your part until we have this information.
What makes this Programmed 16211539 PCM different from a junkyard part?
Our module is tested for functionality, loaded with the latest GM software, and specifically flashed to your car’s VIN. A junkyard part is a gamble—it’s not tested, has outdated software, and is locked to another vehicle’s anti-theft system, which will prevent your car from starting.
Is this the correct part for my car?
Please review the detailed compatibility list on this page. This module fits a wide range of 1996 Buick, Chevrolet, Oldsmobile, and Pontiac models. Matching your vehicle and engine to the list is the best way to confirm fitment.
Will this fix my check engine light?
If the check engine light and associated codes are being caused by a faulty PCM, this part will resolve the issue. However, it’s always recommended to have a proper diagnosis performed to ensure the PCM is the root cause and not another sensor or component.
What if my original part number is 16231853?
No problem. This module is a direct, updated replacement for several service numbers, including 16231853 and 88963800. As long as your vehicle is on the fitment list, this part is the correct one for your repair.
